other spokes and without injury to the ielly oi the 4 wheel. v

Another object of the invention is the provision of a hub that is practically dust-prodi'.

Another ol.,ct is the provision of a hub embodying means for permitting expansion ot' Wood spokes due '1o dampness and ior compensating tor shrinkage of the spokes.

Other objects and advantageous ieatures oi the invention will be fully understood from the .following description and claims when the saine are read in connection with'the accompanying drawings, forming part oil' this specilication, in which:

Figure l is aside elevation olf the hub constituting 'the preferred embodiment of my invention, and showing a spoke properly positioned in the hub. Fig.. 2 is a longitudinal central section oi the same. Fig. 3 is a transverse section taken in the plane indicated by the line 3-3 oi' Fig. l.. Fig. 4 is a transverse section taken in the plane indicated by line 4-4 ol' Fig. l. Figs. 5 and o are similar views on the lines 5*.5 and 6 6, respectively. ol' Fig. ll. Fig.' 7 is a detail perspective view ol the inner portion ol one of the spokes employed in com bination with the hub, Fig. S is a detail section taken at the inner side ol' the head o1 the linch pin.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is an axle spindle having a collar a at its inner end and a dianietrical aperture h at its outer end.

B is the box oi my novel hub which receives the said spindleand is provided at its inner end with a boss cv and on its side with two (more or less) ribs d, and C is a lineh pin arranged ii. the aperture h of the axle spindle and against the outer end of the box'B to hold the box on the spindle.

As best shown iniFigs. 2 and 8, one side of the head or' the linch pin is Hush with the shank oi the pin while the other sides of said head are arranged atV gradually increased distances from the shank. The first mentioned side of the head isdilnitially presented to the end of box B, but when wear takes place one oi the other sides of the head is presented to the end ofthe box according to theamount of Wear toloe taken up.

V'As best shown in Fig. 2, the body of my novel hub is made up of an inner metallic section D, an outer metallic section E, and a metallic annulus F; and the inner e'ndof the hub is rendered dust-proof by a dust band G threaded into the inner end oi' the section D, while the outer' end is rendered dust-proof by a cap H threaded into the outer end oi the section E, Interiorl y the inner section D of the hub` body is providedwith a shoulder e to bear against the boss c on box i3, and longitudinal grooves f to receive the box ribs d. wlnrreby the box is held against turning in the section, and exterimly said section is provided with a square outer end o surrinuided by a flange h, and a circular series ol spaced and equi-distant, longitudinally-disposed projections i extending from the end g and having their outer ends slightly beveled as indicated byj, Fig. 2, forapurposepresentlysetforth. Said inner section D is also provided at It with a diametrieal aperture, and through this aperture loosely extends a tube I which is dctachably threaded through the box l Band is normally.closed a t its outer end` by a screw cap J. When this cap is removed, lubricant. may obviously be conveniently supplied through the tube l to the spindle A. i.

The outer section l oi the hub body which like the section D and annulus Fis made of suitable metal, is threaded at l on the/box B and is providedy on its inner end with a shallow projection m fitted in a corren spending recess 1t in. the outer iace oi the annulus l". Huid secimi li is also provided at p with a longitudinal groove'r. Figs. 2 and 5, ol dovetail l'orm in cross-section, 'and with this groove is designed to be alined a notch s inthe cap H so as to receive a removable fastening bar K, This bar K. holds the cap H against casual disconnection l'roui the body section E; and it is connected to said section E 'by a screw L which extends through a threaded aperture in the section E and is set against the box l so as to hold the section E against casual turning thereon. When itis desired to turn the section E on box B, the screw L must be' turned out ol engagement with box B, while when it is desired to turn the cap ll out ol' the said section E, the fastening bar K must be disconnected from the section E and removed from the groove and notch in the section and cap, respectively. The annulus F of the hub body is provided at t with grooves to receive the ribs don box B, whereby the annulus is held against turning on the box; and said annulus is also provided with an inclined inner iace u, Fig, 2, for an important purpose presently set forth.

M M are the spokes employed in combination with the hub, which spokes are of Wood. The base portions o oi said spokes are vertical at one side w and are inclined at their opposite sides to conform to the in'- clined lace u oi the annulus F, while the other sides o1' Said base portions 'u are 'also shouldered at a; to bear on the outer edges of the projections 'i oi the body section D, and are provided with integral reduced portions y to occupy thespace, between the projections il: the outer edges lz of said reduced portions being also'inclined in vconformity with the inclined inner face of l the annulus Surrounding the projections i of the bodysection D and interposed between. the square end of said section and the vertical sides oi the base portions of the spokes M is'an annulus N of rubber o r other suitable resilient material.

Byr virtue oi the construction described, apparent that theI base portions oi the spokes M present solid wood sides to the metallic annulus F and the rubber annulus N as is desirable for the sake of strength it will be y and durability; also, that the inclined face oi the an" nulus F opposed to the inclined sides'oi` the base portions of the spokes, enables the operator by adjusting the annulus F through the mediumof the outer section E of the hub body to maintain the base portions oi the spokes tightJ and solid *against the resilient annulus N or against the squaref'eiid of the inner section D oi the hub body. l

l'twill further one of the spokes being broken, the section E -oi the hub body may be turned outward and A'then the brokenlspoke maybe readily removed and replaced with a new be apparent that inthe event ofanyl spoke without affecting the other spokes or injuringthe elly4 (not shown) oi the wheel.

The resilient annulus N maybe omitted from my hovelhub without involvingvdeparture from the. scope of my invention as claimed. I prefer, however, to 'e1n' ploy the said resilient annulus since it serves to compensate for shrinkage oi the -wood spokes,and also permits expansion orr swelling of said spokes duc to dampness without liability v0i the spokes being injured by the metallicsections of `the'hub body.

The dust'band G may be formed in oneA piece asI shown,..or in 'two semi-circular sections; the latter being designed for use when it is desired to employ my improvements on an old axle.

It will be noted fromv the foregoing that the box B is readily removable and may, therefore, be expeditiously nai ribs` an vinner body section arranged on the box in enandi easily replaced with a new boxwhen necessity demands. It will also be noted that the hub as a whole is strong and durable and hence well adapted to with stand the shocksand strains towvhich wheel hubs are ordinarily subjected. v f Y i The construction shown andl described constitutes. the preferred embodiment of my invention, but desire it understood that inV practice such changes or modifications may be made as iairly fall Within the scope of my invention as claimed.`

Having described my invention, what I claim and desire to secure by Letters-Patent, is:
